Open Stack

After a user gets authenticated, each following request will have a header
named HTTP_X_SERVICE_CATALOG which contains service end point links, can
any one tell me if it is safe to use the information contained in the
header to get the various end points from a filter in the pipeline? Notice
this header is set in the keystone, any other implementation of keystone
may choose not to include the information in the header, can anyone tell me
putting the endpoints in the headers is required by any implementation like
keystone for authentication?

Thanks.
